This fails with the following error:

===
kpathsea: Illegal fontname `Adobe Garamond Pro': contains ' '
! Font \a="Adobe Garamond Pro" not loadable: Metric (TFM) file not found.
<to be read again>
                   \a
l.1 \font\a="Adobe Garamond Pro"\a

It acts like it's wanting a TFM as Taco suggested, but I don't have
one of those.  I only have a TTF of Adobe Garamond Pro.
